Brief Summary:

The purpose of this study is to see how long it takes for prostate cancer to come back in patients who have had surgery to remove their prostate gland (radical prostatectomy), while being treated with enzalutamide (formerly known as MDV3100).

Enzalutamide is known as an androgen-receptor signaling inhibitor, which means that it blocks activity of the male hormone, testosterone. Most prostate cancers are dependent on testosterone for growth. In this study, patients will take enzalutamide after surgery to see if it keeps their cancer from coming back.

Condition or disease Intervention/treatment Phase
Adenocarcinoma of the Prostate Drug: enzalutamide Phase 2

Detailed Description:

This is a pilot phase II study evaluating the clinical activity and safety of Enzalutamide (formerly known as MDV3100) a novel androgen receptor (AR) inhibitor in men with high-risk prostate cancer who have undergone local definitive therapy with radical prostatectomy.

Primary Objectives:

-To evaluate the clinical efficacy of enzalutamide in patients with high-risk prostate cancer with regards to: Time to disease progression defined by biochemical recurrence (BCR)

Secondary Objectives:

-To further evaluate the safety of enzalutamide in patients with high-risk prostate cancer

Patients will receive daily oral therapy with enzalutamide at 160mg (4 capsules) orally once daily (QD). Patients will continue on study until progressive disease, drug intolerability, consent withdrawal or completion of study at 24 months.

Other Names:
  • MDV3100

Primary Outcome Measures :
  1. Time to progression, defined by serologic criteria. [ Time Frame: 2 years ]
    Serologic criteria is a PSA value > 0.4 in two separate occasions at least two weeks apart.

Secondary Outcome Measures :
  1. Safety of enzalutamide [ Time Frame: 2 years ]
    To further evaluate the number of patients that experience adverse events related to the study drug. NCI Cancer Clinical Trials Common Toxicity Criteria (version 4.0)will be utilized.

Other Outcome Measures:
  1. Impact of enzalutamide on circulating tumor cells (CTCs) [ Time Frame: 2 years ]
    Quantify mRNA levels of Survivin in CTCs obtained from patients pre- and post-treatment with enzalutamide using the Veridex Cell Search Profile kit.

Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Understand and voluntarily sign an informed consent form.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
  • Histologically confirmed adenocarcinoma of the prostate.
  • Patients must have undergone a Radical Prostatectomy (any surgical technique is permitted) within 3 months from study entry and have high-risk disease define by any of the following:

    • Pathological stage T3a, T3b, T4 (any grade or iPSA)
    • Gleason' sum ≥ 8 (any stage or iPSA)
    • Initial Pre-operative PSA ≥ 20ng/mL (any GS or pT stage)
    • Any stage/PSA/Gleason patients with a 35% or greater chance of biochemical failure at 5 years based on Kattan's nomogram
    • Patients with Lymph node (LN) positive disease, regardless of iPSA, pT stage or GS provided their post-operative PSA 6-8 weeks after surgery is ≤ 0.4ng/mL. (Lymph node dissection is desired but not mandated)
  • Able to swallow the study drug and comply with study requirements.
  • Patients must have normal organ and marrow function as defined below:

    • Testosterone ≥ 50 ng/dL per laboratory reference range
    • Baseline Post-RP PSA ≤ 0.4
    • Hemoglobin ≥ 10.0 g/dL independent of transfusion
    • Absolute neutrophil count ≥1,500/mcL
    • Platelet count ≥100,000/ìL
    • Serum albumin ≥ 3.5 g/dL
    • Serum potassium ≥ 3.5 mmol/L
    • Liver function: serum bilirubin < 1.5 x ULN (except for patients with documented Gilbert's disease) and AST or ALT < 2.5 x ULN

Exclusion Criteria:

  • Severe concurrent disease, infection, or co-morbidity that, in the judgment of the investigator, would make the patient inappropriate for enrollment
  • Prior radiotherapy to the prostate or pelvis (related to prostate cancer). Concurrent adjuvant radiation therapy is permitted once patient has been enrolled on trial.
  • Prior use of Abiraterone acetate or cytotoxic chemotherapy for prostate cancer
  • Prior androgen deprivation with Luteinizing hormone-releasing hormone (LHRH) is permitted provided that testosterone levels prior to study entry have recovered to normal limits per reference laboratory.
  • No prior anti-androgen therapy (bicalutamide, flutamide or Nilutamide) is permitted
  • Prior use of 5-alpha reductase inhibitors is permitted provided such medications were stopped 7-14 days prior to enrollment
  • Use of herbal products that may have hormonal anti-prostate cancer activity and/or are known to decrease PSA levels (e.g., saw palmetto) or systemic corticosteroids greater than the equivalent of 10 mg of prednisone per day within 2 weeks of enrollment
  • Active unresolved infection
  • Known history of central nervous system (CNS) metastases
  • Patients must have no known history of HIV
  • Evidence of metastatic disease as evidenced by a CT or MRI of abdomen and pelvis and/or whole body bone scan (WBS). To be done prior to treatment start and up to 4 months prior to radical prostatectomy date.

  • Gastrointestinal disorder affecting absorption (e.g., Gastrectomy, active peptic ulcer disease within last 3 months)
  • Any condition or reason that, in the opinion of the Investigator, interferes with the ability of the patient to participate in the trial, which places the patient at undue risk, or complicates the interpretation of safety data.
  • The effects of enzalutamide on the developing human fetus at the recommended therapeutic doses are unknown. Thus, men must agree to use adequate contraception (barrier method of birth control or abstinence) prior to study entry, for the duration of study participation, and for 6 months after the usage of enzalutamide. Should the patient's partner become pregnant or suspect she is pregnant while the patient is participating in this study, the patient should inform his treating physician immediately.
